Hab. Natal, Mc Ken, No. 11; Plant, 52; Sanderson, Guein- 
zius in herb. Kew. ; Pappe 77 in herb. Lindley. 
All the specimens are imperfect as to leaves. The habit 
appears to be between that of H. Bonatea, Reichb. f., and H. 
cassidea, Reichb. f. Gueinzius’s plants are more slender than 
those of MeKen or Pappe. In structure the flowers must be 
similar to those of H. densiflora, Sond., judging from a drawing 
in Herb. Lindley, but the sepals of that are much narrower and 
more acuminate and the column very different.
